It would not work for me.  I am not multi-homed.  I have a single DSL line to
my upstream provider.  I know in the best of all worlds I would be but I'm not
now.  I think the problem is that there are a fair number of legacy people who
are like me.  They are probably /24s since that was what was given if you
coouldn't justify a /16.
